彩色濾光片是彩色液晶顯示器的必要組件之一，顏料分散型彩色光阻劑(PDCR)則是製造彩色濾光片最重要的原材料。本研究已使用3種甲基丙烯酸酯單體與甲基丙烯酸為原材料，合成符合PDCR所使用的各類共聚合壓克力樹脂，並篩選出市售的數種光起始劑與多官能基高分子單體，加上色母漿料搭配田口實驗法找出最佳符合彩色濾光片製程之紅色、綠色、藍色PDCR。
本研究亦針對PDCR的主成分(壓克力樹脂單體與溶劑混合系統)之密度與黏度做基礎的研究，希望透過熱力學的方法來探討PDCR儲存安定性的問題。我們採用比重瓶及毛細管黏度計，分別量測PDCR用壓克力樹脂單體甲基丙烯酸(MAA)、甲基丙烯酸苯基酯(BzMA)與甲基丙酸2-羥基乙基酯 (2-HEMA)及業界所用之安全溶劑單甲基醚丙二醇乙酸酯(PGMEA)、乙氧基丙酸乙酯(EEP)與環己酮(CHN)的9種混合溶液系統在298.15K、308.15K、318.15K及常壓下的密度與黏度。這些量測數據配合Redlich-Kister polynomial數學式與McAllister動黏度數學模式來關聯，並利用過剩體積(VE)與黏度偏差(dh)來探討壓克力樹脂與溶劑混合系統之分子間作用力對PDCR儲存安定性的影響。
結果顯示，溶劑本身對PDCR主要影響在於PDCR本身整體的黏度，當溶劑的黏度愈大時，則PDCR的黏度也相對的愈大。而溶劑與壓克力樹脂單體兩者間是有作用力存在，但其對PDCR的儲存安定性影響並不大，可能需要進一步了解PDCR各組成間作用力關係，才能對PDCR儲存安定性有更佳解釋。

Color filter is one of essential parts of color liquid crystal display, and the pigment dispersed color resist (PDCR) is the most important material for manufacture of this part. One of the objectives of this research is to synthesize the copolymer acrylic resins which satisfy the specific requirements of PDCR by using three types of methacrylate monomers and methacrylic acid, and with selecting several types of photo-initiator, color paste, multifunctional acrylic monomer, and color paste has been explored for preparation of the PDCR. We found the favorable formulas, PDCR, which satisfied the process of manufacturing color filter with respect to red, green and blue by using the Taguchi method.
The other objectives of this research focused on the base study about densities and viscosities of the key compositions (blended system of acrylic monomer and solvent) of PDCR, and hoped to discuss the problems of storage stability of PDCR by thermodynamic methods. We use pycnometer and Cannon-Fenske type viscometer respectively to measure the densities and viscosities for the nine binary systems composed of the acrylic monomers that are methacrylic acid (MAA), benzyl methacrylate (BzMA), and 2-hydroxyethyl methacrylate (2-HEMA) and safety solvents that are propylene glycol monomethyl ether acetate (PGMEA), ethyl 3-ethoxypropionate (EEP), and cyclohexanone (CHN) at 298.15K, 308.15K, 318.15K, and 1 atm. The excess molar volumes VE and viscosity deviations dh were calculated from the experimental data and were correlated by a Redlich-Kister type polynomial and McAllister’s models. For the influences about storage stability of PDCR, the inter-molecular force was discussed by means of the variations of excess volumes and viscosity deviations in the above-mentioned binary systems.
The result of the inter-molecular force in the binary systems shows that the viscosities of PDCR increase monotonically with an increase of viscosities of solvent. We all know that the inter-molecular force between solvent and acrylic monomer is existence, but their influences for storage stability of PDCR are very small according to our experimental results. For giving a best explanation about storage stability of PDCR, we should need to understand their interaction involved in all compositions of PDCR as possible.
